The following dissertation on Oscar is from notes prepared by Samuel Gunnett Neff from his publication on the Neff-Gunnett-Crow families:

Oscar Raymond "Dewey" Crow was born at Borden Mines, MD.  He was the third and youngest son of George Maxwell Crow.  As a youth he worked for the Borden Mining Co. as a stable boy and hostler under the supervision of his father who was the stable boss and veterinarian.
He moved with his mother and brothers after the death of his father to Ellwood City, PA in 1917.  Within a short period of months he joined the U.S. Army and served with the 7th Calvary in Texas and Mexico during the Poncho Villa incident.  This service in the Calvary was a natural outgrowth of a youth spent as a hostler and aid to his father at the Borden Mining Company Stables. 
Following the war he was a member of the 107th Field Artillery, Pennsylvania National Guard, and Dewey later was employed as a steelworker and a city policeman in Ellwood City, PA.  Later he lived in retirement in Los Angles and passed away in that city in 1964.  He married Ester Fike in 1924, following a divorce from Esther in 1930; he married Nora Parsons of Beaver Falls, PA.  He moved to California in 1956 and died in 1970, (See correct date of death below).
My Uncle Dewey was a great fellow, he was a quarter Indian, dark complexion, handsome at six feet and 180 pounds only 13 years my elder generally speaking I had a closer relationship to him than to others of his generation.  We were good friends, he was a good athlete nicknamed 'Smoky' because as a baseball player, he had a good arm making for a good pitcher or third baseman.  He appreciated my abilities as a young ballplayer; the first baseball suit I ever owned was given to me by Uncle Dewey.  It had been his when he played for the Ellwood City Eagles.
He was gregarious lovable guy, loved the spirits a little too much and had an aversion to steady employment.  He enjoyed the immaturities of youth so much that he refused to accept the responsibilities of adulthood, be that as is may, he enjoyed doing it his way and departed this life leaving a legacy of love and affection tucked away in the heart of a nephew - Samuel Gunnett Neff."
